The Shattering of Azeroth has been live for over 24 hours, and Blizzard has received many reports of bugs in Cataclysm Classic.
While some of these issues have been addressed, Blizzard is continuing to work on various Class bugs, Heirloom items scaling improperly, and PvP inconsistencies.
Issues addressed: Some pet classes will have their pet action bar missing after relogging. New pets that hunters tame that are lower level than the hunter will not properly level up to match the hunter’s level automatically.
Some pet classes may have their pet action bar missing after logging out in a non-rested area. Feral druid weapon normalization is not functioning properly, resulting in druids doing more damage than intended.
Some spells are missing from players’ spellbooks, or located on the wrong page, or are appearing when they do not exist in Cataclysm.
